Analysis of the Impact of Economic Growth on Urban Land Expansion in Sichuan Province

Abstract

Based on the panel data of the urban land expansion and economic growth of 18 prefecture- level cities in Sichuan province from 2000 to 2014, this paper analyzes the relationship between the regional economic development and urban land expansion by constructing the econometric model of the area of the built-up area, the economic aggregate and the economic structure variables. The results show that: (1) The evolution law of urban land expansion and economic growth in Sichuan province "N" three times, which basically conforms to the characteristics of Kuznets curve; (2) The change of economic structure will affect the urban land expansion and the area of built-up area - per capita income curve.The increase of the proportion of secondary industry, fiscal expenditure and fiscal revenue will reduce the demand for urban land, so that the area of built-up area - per capita income curve flattens out. On the contrary, the increase in the level of foreign trade, the increase of input-output ratio and the decline of the proportion of the tertiary industry will increase the demand for urban land, making the built-up area - per capita income curve steeper.
